SCUTTLE-DOOR AND SKYLIGHT LIFTER.

Specification of Letters Patent.

Patented Sept. 19, 1:105.

Application filed May 2.1905. Serial No. 258,526.

To all whom, it 717/1 concern..-

Be it known that I, JOHN D. BEE, Jr., a citizen of the United States, residing at West Lynn, in the county of Essex and State of Massachusetts, have invented a new and use ful Scuttle-Door or Skylight Lifter, of which the following is a specification.

The present invention has particular reference to means for eflecting the movements of skylights, scuttle-doors, or other analogous devices that are ordinarily out of reach.

The object is to provide an exceedingly simple device of a novel nature which can be readily and cheaply manufactured, easily applied by a person of ordinary intelligence, is effective and durable, and is not liable to derangement.

' The preferred form of construction is illustrated in the accompanying drawings, where- Figure 1 is a sectional view through a skylight and curb with the elevating means in place and showing the skylight closed. Fig. 2 is a similar view, but showing the skylight elevated and the guide in section. Fig. 3 is a front elevation, on an enlarged scale, of a portion of the mechanism; and Fig. i is aplan view of the guide.

Similar reference-numerals designate corresponding parts in all the figures of the draw ings.

In the embodiment illustrated an ordinary type of skylight 5 is shown, which is hinged at 6 to the upper edge of the curb 7. The structure and arrangement of the skylight is not important and may be changed as desired. Furthermore, the invention may be employed in connection with scuttle-doors and the like.

An elevating-rod 8 is hinged, as shown at 9, to the free margin of the skylight and extends downwardly within the curb, slidably passing through a guide, which is designated as a wholeby the reference-numeral 10. This guide preferably consists of a single piece of sheet metal, the opposite side margins of which are doubled inwardly, as shown at 11, thereby forming a base having suitable openings 12 to receive fasteners. The terminal portions of the sheet metal are outturned to form guide-walls 13, whichhave offset flanges 14 arranged in opposing relation and spaced apart to provide a slot 15. By reference to Figs. 1, 2, and 3 it will be noted that the side walls 13 are wider at their-upper than at their lower ends. The lower portion of the elevating-rod 8 slidably passes through the guide, being embraced by the walls 13 .and flanges 14, the guideway thus formed being wider at its upper end to permit the necessary play of the rod. A pulley 16is secured to the base at one side of the guideway, this portion of the base being preferably wider than that on the other side, as shown in Figs. 3 and 4t, An operating-cord 17 passes about the pulley 16 and is secured in an eye 18, carried by the lower portion of the elevatingrod 8, which eye is movable into the slot 15 when the skylightis elevated. Another cord or cable 19 is secured in the eyes 18 and drops directly therefrom to a point within convenient reach of the operator.

It will be apparent that when the cord 17 is pulled downwardly the rod 8 will be elevated, thereby opening the skylight, and when said cord is released the weight of the skylight will close the same, thereby carrying the rod 8 downwardly to the position illustrated in Fig. 1. If for any reason the skylight should fail to drop of its own weight, it can be drawn downwardly by the cord 19, and said cord constitutes means whereby the said skylight can be fastened in closed position. By this means an exceedingly simple device is provided which can be readily and cheaply manufactured, is easily applicable to the curb of the skylight, and the parts being simple is not liable to derangement.

From the foregoing it is thought that the construction, operation, and many advantages of the herein-described invention will be apparent to those skilled in the art without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination with a door or window to be opened, of an elevating-rod hinged thereto, a guide for said rod having outstanding tapering side walls provided with ofiset opposing flanges, the inner edges of which are spaced apart forming a slot, said walls and flanges embracing the rod, a pulley located at one side of the guide, a cable passing over the pulley, and a device for connecting the cable to the lower portion of the elevatingrod, said device being movable in the slot and between the flanges.

2. The combination with a door or Window to be opened, of an elevating-rod hinged thereto, a guide for said rod formed of sheet metal having its side margins doubled to form a base and outturned to provide guide-walls, said guide-walls being Wider at their upper than their lower ends, and having opposing flanges spaced apart to form a slot, said elevating-rod passing between the guide-walls, an eye secured to the lower portion of the elevating-rod and movable in the slot of the guide, a pulley fastened to the base at one side of the guide, and a cable passing about the pulley and secured to the eye.

3. The combination with a door or window to be opened, of an elevating-rod hinged thereto, a guide for said ro'd formed of sheet metal and having between its side edges outstanding walls wider at their upper than their lower ends and embracing the rod, a pulley secured to the guide at one side of the out-standing walls, and an operating-cable passing about the pulley and connected to the elevating-rod.

In testimony that I claim the foregoing as my own I have hereto ai -fixed my signature in the presence of two witnesses.
